Product Line Details: Centric Premium High Carbon Alloy Disc Brake Rotors

The Centric Premium High Carbon Alloy Disc Brake Rotors line focuses on high carbon alloy construction to enhance rotor strength and wear resistance. This product line is designed to provide improved thermal stability and reduced brake fade under demanding driving conditions. The 125.34091 rotor benefits from this advanced metallurgy, making it suitable for BMW vehicles requiring reliable, long-lasting braking components.

Technical Description and Specifications

This disc brake rotor features a vented design that promotes efficient heat dissipation, reducing the risk of warping during heavy braking. The rotor has a nominal thickness of 20.000 mm and a discard thickness of 18.400 mm, ensuring it meets safety standards for replacement intervals. The coated hat finish protects against corrosion, extending the rotor's service life. With a 5-bolt hole pattern on a 120 mm bolt circle diameter and a center hole diameter of 75 mm, this rotor is engineered for precise fitment on compatible BMW models. The smooth surface type ensures even brake pad wear and consistent braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 130i, 325xi, 328i, 328i xDrive, 328xi, and X1
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves braking consistency and reduces noise
• Prevents premature rotor wear due to corrosion or heat damage
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.400 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants. Verify the 5-bolt hole pattern and 120 mm bolt circle diameter match the vehicle hub. Use proper torque specifications when mounting the rotor to avoid warping. This rotor does not include bearings or an ABS tone ring, so verify compatibility with your vehicle's braking system.
